A North Korean missile attack on the US is inevitable, according to the UN Secretary-General's speech, by his foreign minister. The "visit of our missiles throughout the US mainland has become inevitable," said Ri Yong Ho in his speech to the United Nations General Deputy on Saturday in New York. North Korea will take "relentless, preventive steps" if the US attempts to "head" the headquarters in Pyongyang or the North Korean military. In his speech Ri countered the hard rhetoric of trumps with similarly sharp tones. "No one but Trump himself is on a suicidal mission," Ri said, quoting Trump's attack on North Korean leader Kim Jong Un. Trump had described Kim as a "rocket man on a suicidal mission." Trump lacked "basic general knowledge". If innocent Americans were to be hurt in the conflict between the two countries, Trump is "totally responsible." North Korea is on its way to a nuclear war, and is also "responsible," Ri said State. "Our ultimate goal is to create a balance of power with the US," said Ri.USA, bombers to leave North Korea. In the conflict around the North Korean nuclear weapons program, the US on Saturday have several B-1B bombers from Guam and fighter jets into the international airspace east from North Korea. It was the first time this century that American combat aircraft or bombers had flown to the north of the demilitarized zone off the North Korean coast, the Pentagon said. "The mission is a demonstration of American determination and a clear message that the President (Donald Trump) has many military options to tackle any threat," continued the United States. "We are ready to use the full range of military capabilities to protect our home country and our allies." The conflict between North Korea and the US on the missile and nuclear tests of Pyongyang continued on Friday. In response to the warlike tones of Trump before the United Nations, Kim Jong Un, the North Korean leader, declared: "I will undoubtedly undermine the spirit-minded, demented US-old man." (Dpa)
